This species ranges from extreme southeastern Nigeria through central and southern Cameroon to Equatorial Guinea, central Gabon and southwestern Central African Republic to the Democratic Republic of Congo. It occurs below 1,200 m asl. Its eastern distributional limits in the Democratic Republic of Congo are particularly unclear. It is presumed to occur in Congo, and this is included on the map.

It lives in moist lowland and lower montane forest, and cannot survive in degraded habitats. It is found in mature secondary forest. The animals are usually found on the ground, or in plants up to 20 cm above ground. They breed in forest streams and the males call from slopes and marshy depressions close to streams.
